I mean, c’mon. This is Objective-C we’re talking about, not Java or C++. However, until Objective-C 2.0’s property support hits the streets (which, unfortunately, will only be supported on Mac OS X 10.5 and later as far as I know), you really have to write these dumb-ass accessors to, well, access properties in your objects correctly. You don’t need to write accessors thanks to the magic of Cocoa’s Key-Value Coding, but it just feels wrong to access instance variables using strings as keys. I mean, ugh—one typo in the string and you’ve got yourself a problem. Death to dynamic typing when it’s totally unnecessary.

As such, I got totally fed up with this and wrote a little script to generate accessor methods. I’m normally not a fan of code generation, but in this case, the code generation’s actually designed to be one-shot, and it doesn’t alter the ever-picky build process. It’s meant to be used in Xcode, although you can run it via the commandline too if you like.

Done. You should now have a Scripts menu in Xcode with a new menu item named “IVars to Accessor Methods”. Have fun.

1 Note that older versions of the Cocoa Coding Guidelines specified that prefixing instance variables with underscores is an Apple-only convention and you should not do this in your own classes. Now the guidelines just don’t mention anything about this issue, but I still dislike it because putting underscores every time you access an instance variable really lowers code readability.
